Arduino can be used to communicate with a computer, another Arduino board or other microcontrollers. The ATmega328P microcontroller provides UART TTL (5V) serial communication which can be done using digital pin 0 (Rx) and digital pin 1 (Tx). An ATmega16U2 on the board channels this serial...
1. Power 输入电压具有6V~12V宽电压输入、USB 5V输入、VIN输入。 输出电压具有5V/3.3V可切换(J1跳Pin),IOREF输出 (MCU工作电压),而Arduino UNO R3 官方版只有5V。 注:当外部模块需要功率大时,请使用独立供电。如连接电机需要使用专门的驱动板,而不能直接用GPIO去驱动。
利用pinMode()、digitalWrite()和digitalRead()功能,Uno上的14个数字引脚都可用作输入或输出。它们的工作电压为5V。每个引脚都可以提供或接受最高40 mA的电流,都有1个20-50 kΩ的内部上拉电阻器(默认情况下断开)。此外,某些引脚还具有特殊功能:· 串口:0(RX)和1(TX)。用于接收(RX)和发送(TX)TTL串口数据。
